Tax return is in. Looking at completing the turbo swap. Have decided to go way of Romulator management for the turbo. Have this ecu that is straight from JWT. It was originally programmed for stock 300zx injectors, then I sent it back because I upgraded to 370cc injectors and had the ecu reburned. It will utilize stock Max MAF. The ecu has all the JWT markings on it. This is out of an '89 5sp Max. Here are the ecu numbers: A18-A12 E70 (72). I even have the stock max chip if anyone wants it (JWT sends it back with the ecu). We all know the cost of the programming of these units, make a reasonable offer. Email me directly to facilitate quicker responses: Mxmumpwr@aol.com

 

Clarification: ecu is programmed for 370cc injectors, they are not included.

 

If you want to emulate your EPROM with ease, I HIGHLY recommend the Zemulator system. I just want to make sure you already know about it and that it works for your ECU.

The Zemulator works great on all 8 bit Nissan ECUs including the VG30E Maxima and early z32s. It was originally designed for 8 bit z32 ECUs, but it will plug right into your VG ECU, which is 8 bit. The only difference might be that you can't tune for an optimal VTC release point, b/c of course, the VG30E lacks that. That is the only thing I can possibly think of that would be different about the software. Full control over your ECU is a great thing.

Me and Ash are currently working on getting it to work on the late model z32s and the VE Maxima, which are 16 bit ASIC ECUs without an EPROM.

But if you already know how to interpret the code and don't mind the extra time it takes to tune, then you can go with a normal emulator. That should work just fine and will save you a few bucks on the system.

 

romulator + livedit=

if you have any questions on this setup, feel free to PM me about it

I've already spoken to a couple of guys about LiveEdit. I am ordering the Romulator in the next couple of days. I already have the laptop and Live Edit uploaded and installed. Have also already (with help from its creator!) modified the program to run the VG30E before swapping over to the turbo. I just need to find someone who can solder in the Romulator.

So, any interest in the already programed ECU?

 

dont solder in the romulator... solder in a socket to plug the romulator into...

 

I'm sure that's what he meant. Or at least I hope he did. You definitely need a socket.

 

LOL! Yes, I did mean a socket! Just haven't found anyone yet. Will try Monday since I'm off work for the day. I've also just visited Lawrence's site today. He has a new version of LiveEdit it seems. I've downloaded it but not installed it yet, there may be no difference. BTW: I did recieve my Romulator today and have downloaded the software for it. Will be pulling my ecu tomorrow.

 

Please keep us updated on how it goes. I am especially interested in this.

 

you may already be aware of this... but.. the Live edit software will connect with the Romulator directly so you dont need to go thru the romulators programs. quite nice actually. also, after you do the " upload to emulator" function, dont forget to turn the ignition off before trying to start the car. Ive heard of a few people haveing trouble with this. Just thought id throw some info out there.
Hope it all goes good for you.

Good luck
Jeremy

 

Jeremy,
Thanks. Actually, I didn't know that the Live Edit would go right into the romulator. I thought you had to have the Romulator program running in background. Good to hear...saves room on my laptop! I am a bit confused about the instructions on the romulator about initial startup, something about keying in codes to initialize that the laptop has found the romulator. Is this even necessary with Live Edit? Right now, I'm just trying to install version 3.0 of Live Edit. For some reason it won't let me. I'm going to try and install it like you have to do with the previous beta version. Nice info, thanks!
BTW, not sure if it's a design flaw, but my cord that they sent with it does not fit the Romulator. It looks like the connector on the Romulator itself is set too far to one side which causes the cord to bump the casing. I will open up and see if I can remedy this. Is there a for sure USB adaptor that works? I keep hearing that some do/others don't.

 

KnightRaven: Just responded to your email. got it before seing your post here.
UpDate: Got socket soldered in and Romulator installed. Mounted the unit atop the ecu with screws pointing up so I can access (change battery, etc). Ran computer cord through glove box and installed a ground where the cord attaches to the Romulator to help protect against static discharge. Uploaded Bernard's moded program he gave me for the Max. I have yet to install the z32 MAF, however, car ran pretty good....VERY rich though....most likely becuase still using stock MAF. Was able to take down the road. Rewired the mess of wired behind stereo while in there. I've got like 3 relays, alarm, stereo, AVC-r boost controller....just a mess! All cleaned up now. I installed the distribution blocks for positive and one for negative (ground) on the panel beneath the steering wheel. Very clean looking!
However, I've still not been able to install Live Edit 3.0 edition. Not sure why. Any help guys?!

 

sounds like your getting it under control nicely... as for the live edit. go to http://Redz31.com and down load the live edit version he has available. i belive he still has it on there. thats the one that works for me (as long as he didnt change it).

Jeremy

 

are you installing live edit final? that's the one you want. it's got a bunch of little glitches fixed up. www.romeditor.com is where you want to download it.

 

ive tryed the live edit final a few time, cant get it to work more than a few minutes, who knows its probably my computer

Jeremy

 

Bernardd, I have already installed and played with the Live Edit Beta version for weeks now. However, I downloaded the "Final" version and it will not install. Trying to figure out how to install final over the beta version. Do I need to un-install the older version completely before installing the final? Beta version is running my car presently, but would like to have most recent edition to work from. Any help is appreciated.
Bernardd, do you think if I change my "k" value that I can effectively compensate for how rich I'm running presently while using stock MAF versus the z32 MAF that Live Edit has selected? Anyone have source for z32 Maf?!

 

If you never actually told live edit to switch to the z32 maf you will still have the VQ map for the maxima maf in the ecu... it just displays it as z32 for some reason. Also if your worried you might have the wrong VQ map in, just select the RB20DET maf, its the same as a maxima maf. but if your useing a base maxima program to start with, you shouldnt have to change anything. If you have any other question feel free to Instant message me.

 

Live Edit final doesn't go over the other versions. Install it into it's own directory. You need to check and make sure you have the z32 vq map. If not it's best to start over with the stock binfile for a new user. The tp scales get all skewed if you keep making changes. Lets assume you have the z32 vq map installed, the kvalue set for size injectors and haven't touched any other mapping. First set your o2 activation temp to FF to keep it from going into closed loop and making corrections. Will have to do this in romeditor or a hex editor as Live Edit doesn't have that function mapped. Next set the entire fuel map to 0. The goal here is to have all fueling set to a 14.7 afr. DO NOT PUT TOO MUCH LOAD ON THE CAR WITH FUEL MET SET TO THESE VALUES. Now you can start the car and go for a cruise taking note of the afr's between 2500 and 3k or so. Adjust the kvalue to get the afr's in line. Once you've got that set, park the car to set the injector latency. You'll want to adjust it to get the afr to 14.7 at idle. Repeat until targets are achieved. Now take the kvalue you've got divide the new k by the stock k. Apply this decimal to each tp scale in the fuel maps and the ignition maps and you'll have stock drivability/fuel mileage. You can double check the settings by setting the afr's in the fuel map to 12.5 and repeating the above procedure. After you're happy with the settings reset the fuel map. You willnot be tuned for boost at this point. You'll still need to tune that area. Hope that's clear. If you're going to tune for boost we start another thread to go thru that.

 

Do I have to un-install the previous Live Edits? I've tried to install Final but it keeps giving me an error message. I've even tried to click the Install program in the Live Edit Final file. It keeps saying it cannot/failed to install. This is the same error message I got when trying to open the beta version or something gets put in wrong in Live Edit and it shuts down/won't re-open. Error 13 if I recall.

 

make a live edit directory on your main (C:?) drive. extract the zip file to that. hit the install.

 

Got Live Edit Final installed and running. Felt a bit fumbly getting used to new emulator tab on startup. Seemed to have difficulty initially finding the Romulator, but got it working well once got everything going. Tried to run using the RB MAF, but it started for about 3 seconds and died...wouldn't idle. No big deal, just thought I might try and work out the issue and learn about editing some more. Actually, goal was to just get the car running and moving so that I can get it parked and situated in my garage so I can start tearing peices off the engine that I need for the VG30ET swap (ie. valve covers, oil pan, and intake) and pull the engine. Thanks for all the input!
